Accounting Policies [Abstract]
Background and Summary of Significant Accounting Policies	Background and Summary of Significant Accounting Policies Background Vishay Precision Group, Inc. (“VPG” or the “Company”) is an internationally recognized designer, manufacturer and marketer of sensors, and sensor-based measurement systems, as well as specialty resistors and strain gages based upon the Company's proprietary technology. The Company provides precision products and solutions, many of which are “designed-in” by its customers, specializing in the growing markets of stress, force, weight, pressure, and current measurements. Principles of Consolidation The consolidated financial statements include the accounts of the individual entities in which the Company maintained a controlling financial interest. For those subsidiaries in which the Company’s ownership is less than 100 percent, the outside stockholders’ interests are shown as noncontrolling interests in the accompanying consolidated balance sheets. All transactions, accounts, and profits between individual members comprising the Company have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates. Revenue Recognition The Company derives substantially all of its revenue from product sales. The Company recognizes the vast majority of its sales at a point-in-time. It utilizes the core principle of recognizing revenue when the Company satisfies performance obligations as evidenced by the transfer of control of its products to the customer. Such revenues are derived from purchase orders and/or contracts with customers. Each contract has the promise to transfer the control of the products, each of which is individually distinct and is considered the identified performance obligation. As part of the decision to enter into each contract, the Company evaluates the customer’s credit risk, but its contracts do not have any significant financing components, as payment is generally due net 30 to 60 days after delivery. In accordance with contract terms, revenue from the Company’s product sales is recognized at the time of product shipment from its facilities or delivery to the customer location, as determined by the agreed upon shipping terms. Under the terms of some of its contracts, the Company may be required to perform certain installation services. These installation services are performed at the time of product delivery or at some point thereafter. The installation services do not significantly modify the product provided, and although the Company may be required contractually to provide these services, the installation services could be performed by a third party or the customer. Thus, these installation services are a distinct performance obligation. In most of the applicable contracts, this installation service element is immaterial in the context of the agreement. When the installation services are accounted for as a separate performance obligation, the Company allocates the transaction price to this element based on its relative standalone selling price. Given the specialized nature of the Company's products, the Company generally does not allow product returns. Shipping and handling costs are recorded to Costs of product sold when control of the product has transferred to the customer. The Company offers standard product warranties. Warranty related costs continue to be recognized as expense when the products are sold. Sales, value add and other taxes collected concurrent with revenue-producing activities are excluded from revenue. See Note 2 for further details on Revenues. Research and Development Expenses Research and development costs are expensed as incurred. The amount charged to expense for research and development was $12.6 million, $12.1 million, and $11.8 million for the years ended December 31, 2020, 2019, and 2018, respectively. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income tax expense in the period that includes the enactment date. The Company records net deferred tax assets to the extent it believes such assets will "more likely than not" be realized. In making this determination, the Company considers all positive and negative evidence, including historic earnings, projected future income, and cost-effective tax-planning strategies. When the Company determines that its ability to realize deferred tax assets is not "more likely than not", the Company adjusts its deferred tax asset valuation allowance, which increases income tax expense. The Company records uncertain tax positions on the basis of a two-step process in which the Company first determines whether it is "more likely than not" that the tax positions will be sustained based on the technical merits of the position and then measures those tax positions that meet the more-likely-than-not recognition threshold. The Company recognizes the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense in the accompanying consolidated statements of operations. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets. On December 22, 2017, the SEC staff issued SAB 118 to address the application of U.S. GAAP in situations when a registrant does not have all the necessary information available to prepare and analyze the accounting treatment for the proper recognition of the tax impact of the 2017 Tax Act. In accordance with SAB 118 guidance, the Company had recorded the provisional tax impacts related to the deemed distribution of foreign earnings and the expense for the revaluation of deferred tax assets and liabilities in its consolidated financial statements for the year ended December 31, 2017. In accordance with SAB 118, the financial reporting impact of the 2017 Tax Act was completed in the fourth quarter of 2018 resulting in a net increase in tax expense of $0.8 million. Cash and Cash Equivalents Cash and cash equivalents include demand deposits and highly liquid investments with original maturities of three months or less when purchased. Highly liquid investments with maturities greater than three months are classified as short-term investments. There were no investments classified as short-term investments at December 31, 2020 or 2019. Allowance for Credit Losses The Company maintains an allowance for credit losses resulting from the inability of its customers to make required payments. In determining the amount of the allowance for credit losses, the Company considers historical loss data, customer specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. The allowance for credit losses was $0.9 million and $0.6 million at December 31, 2020 and 2019, respectively. The credit loss was $0.3 million, $0.1 million, and $0.0 million for the years ended December 31, 2020, 2019, and 2018, respectively. Inventories Inventories are stated at the lower of cost, determined by the first-in, first-out method, or market based on net realizable value. Inventories are adjusted for estimated excess and obsolescence and written down to net realizable value based upon estimates of future demand, technology developments, and market conditions. Property and Equipment Property and equipment is carried at cost and is depreciated principally by the straight-line method based upon the estimated useful lives of the assets. Machinery and equipment are being depreciated over useful lives of seven twenty three Business Combinations The Company allocates the purchase price of an acquired company, including when applicable, the fair value of contingent consideration between tangible and intangible assets acquired and liabilities assumed from the acquired businesses based on estimated fair values, with any residual of the purchase price recorded as goodwill. Third party appraisal firms and other consultants are engaged to assist management in determining the fair values of certain assets acquired and liabilities assumed. Estimating fair values requires significant judgments, estimates and assumptions, including but not limited to: discount rates, future cash flows and the economic lives of trade names, technology, customer relationships, property, plant and equipment, as well as income taxes. These estimates are based on historical experience and information obtained from the management of the acquired companies, and are inherently uncertain. Goodwill and Other Intangible Assets Goodwill and indefinite-lived trademarks are tested for impairment at least annually, and whenever events or changes in circumstances occur indicating that it is "more likely than not" impairment may have been incurred. The Company has the option to first assess qualitative factors to determine whether it is "more likely than not" that the fair value of a reporting unit is less than its carrying amount as a basis for determining if it is necessary to perform the quantitative goodwill impairment test. However, if the Company concludes otherwise, then it is required to perform the quantitative impairment test by calculating the fair value of the reporting unit and comparing it against its carrying amount. If the fair value exceeds the carrying value, no further evaluation is required and no impairment loss is recognized. An impairment charge would be recognized to the extent the carrying amount of goodwill exceeds the reporting unit fair value. The indefinite-lived trade names are tested for impairment either by employing the qualitative approach outlined above, or by comparing the carrying value to the fair value based on current revenue projections of the related operations, under the relief from royalty method. Any excess carrying value over the applicable fair value is recognized as impairment. Any impairment would be recognized in the reporting period in which it has been identified. The Company's required goodwill and indefinite-lived asset annual impairment test is completed as of the first day of the fourth fiscal quarter each year. As more fully described in Note 4 to the consolidated financial statements, the 2020 annual impairment test resulted in an impairment charge in the fourth quarter of 2020. The 2019 annual impairment test resulted in no impairment. The 2018 annual impairment test resulted in an impairment charge in the fourth quarter of 2018. Definite-lived intangible assets, such as customer relationships, patents and acquired technology, non-competition agreements, and certain trade names are amortized on a straight-line method over their estimated useful lives. Patents and acquired technology are being amortized over useful lives of seven five seven five Impairment of Long-Lived Assets The carrying value of long-lived assets held-and-used, other than goodwill and indefinite-lived intangible assets, is evaluated when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from such asset group are separately identifiable and are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset group. Fair market value is determined primarily using present value techniques based on projected cash flows from the asset group. Losses on long-lived assets held-for-sale, other than goodwill and indefinite-lived intangible assets, are determined in a similar manner, except that fair market values are reduced for disposal costs. Foreign Currency Translation The Company has significant operations outside of the United States. The Company's operations in Europe, Canada, and certain locations in Asia primarily generate and expend cash in local currencies, and accordingly, these subsidiaries utilize the local currency as their functional currency. The Company’s operations in Israel and certain locations in Asia primarily generate cash in U.S. dollars, and accordingly, these subsidiaries utilize the U.S. dollar as their functional currency. For those subsidiaries where the local currency is the functional currency, assets and liabilities in the consolidated balance sheets have been translated at the rate of exchange as of the balance sheet date. Revenues and expenses are translated at the average exchange rate for the year. Translation adjustments do not impact the consolidated statements of operations and are reported as a separate component of accumulated other comprehensive loss within the statement of comprehensive income. Foreign currency transaction gains and losses are included in the results of operations. For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency financial statement amounts are remeasured into U.S. dollars. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in the consolidated statements of operations. Share-Based Compensation Compensation costs related to share-based payments are recognized in the consolidated financial statements. The amount of compensation cost is measured based on the grant-date fair value of the equity instruments issued. For service-based awards, compensation cost is recognized over the period that an officer, employee, or non-employee director provides service in exchange for the award. The Company recognizes forfeitures as they occur. For performance based awards, the Company recognizes compensation cost for awards that are expected to vest based on whether performance criteria are expected to be met. For options and restricted stock units subject to graded vesting, the Company recognizes expense over the service period for each separately vesting portion of the award as if the award was comprised of multiple awards. Leases The Company determines if an arrangement is or contains a lease at inception or modification of such agreement. The arrangement is or contains a lease if the contract conveys the right to control the use of the identified asset for a period in exchange for consideration. Lease right of use assets and liabilities are recognized based on the present value of future minimum lease payments over the expected term at commencement date. As the implicit rate is not determinable in most of the Company's leases, the Company's incremental borrowing rate is used as the basis to determine the present value of future lease payments. The expected lease terms include options to extend or terminate. The period which is subject to an option to extend the lease is included in the lease term if it is reasonably certain that the option will be exercised. Some of these leases contain variable payment provisions that depend on an index or rate, initially measured using the index or rate at the lease commencement date and are therefore not included in our future minimum lease payments. Variable payments are expensed in the periods incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. The Company uses the practical expedients to exclude from balance sheet reporting leases with initial terms of 12 months or less and to exclude non-lease components from lease right of use assets and corresponding liabilities. Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13, and subsequent related amendments to ASU 2016-13, replace the existing incurred loss impairment model with an expected loss model that requires the use of forward-looking information to calculate credit loss estimates. The Company adopted this ASU, effective January 1, 2020, using the modified retrospective approach, and the effect on the Company's consolidated condensed financial statements and related disclosures was not material. In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurements (Topic 820)." This ASU modifies the disclosures on fair value measurements by removing the requirements to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and the policy for timing of such transfers. The ASU expands the disclosure requirements for Level 3 fair value measurements, primarily focused on changes in unrealized gains and losses included in other comprehensive income. The Company adopted this ASU effective January 1, 2020, and the effect on the Company's disclosures in its consolidated financial statements was not material. In August 2018, the FASB issued ASU No. 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." This ASU amends Accounting Standards Codification ("ASC") 715 to add, remove and clarify disclosure requirements related to defined benefit and pension and other postretirement plans. The Company adopted this ASU effective January 1, 2020, and determined that the effect on the Company's disclosures in its consolidated financial statements was not material. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU No. ASU 2019-12, "Simplifying the Accounting for Income Taxes". This ASU amends Accounting Standards Codification ("ASC") 740 by removing certain exceptions to the general principles, clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020 and early adoption is permitted. The Company has not yet adopted this ASU.

("DSI"), a provider of specialized dynamic thermal-mechanical test and simulation systems used to develop new metal alloys and optimize production processes, for a purchase price of $40.3 million, subject to customary adjustments. During the second quarter of 2020, the Company received $0.2 million from escrow as a purchase price adjustment, resulting in a reduction of goodwill. Additionally, it was determined that an earn out, which was part of the purchase price, was not achieved. DSI reports into the Company's Weighing and Control Systems segment.

Goodwill and Other Intangible A

Goodwill and Other Intangible Assets	12 Months Ended

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The Company has four reporting units to which goodwill is allocated: steel, on-board weighing, instrumentation, and DSI. For the steel and on-board weighing goodwill reporting units, the Company performed the qualitative assessment, which included assessment of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, and other entity specific events which could impact the reporting unit. Based on this review, it was determined that the fair value of each of those reporting units was in excess of its carrying value and therefore no quantitative impairment test was required. For the instrumentation and DSI goodwill reporting units, the Company performed the quantitative impairment test. In estimating the fair value of our instrumentation and DSI reporting units the Company used the income approach. It further uses the market approach to evaluate the estimated fair value of the reporting units that was obtained by using the income approach. The income approach to valuation requires management to make significant estimates and assumptions related to future revenues, profitability, working capital requirements and selection of discount rate and long term growth rate. Changes in these estimates and assumptions could have a significant impact on the fair value of the reporting units. The Company's required goodwill and indefinite-lived asset annual impairment test is completed as of the first day of the fourth fiscal quarter each year. In 2020, the results of the quantitative impairment test for the DSI reporting unit indicated no impairment, with the fair value exceeding the carrying value by approximately 12% for goodwill and 16% for the indefinite-lived trade name. The results of the quantitative impairment test for the instrumentation reporting unit's goodwill and indefinite-lived trade name indicated an impairment, and in the fourth quarter of 2020, the Company recognized a non-cash impairment loss of $2.4 million. The impairment was driven mainly by changes in forecasted projections including a slower growth rate in revenues. After considering the impact of the impairment charges, the carrying amount of goodwill and indefinite-lived trade names as of December 31, 2020 was $1.1 million and $0.4 million, respectively. The Company's analysis in 2019 resulted in the fair value exceeding the carrying value for all reporting units. In 2019, the Company did not recognize an impairment for the instrumentation reporting unit, as the fair value exceeded its carrying value by approximately 12%. During 2018, the Company recognized a non-cash impairment loss associated with the goodwill and indefinite lived intangible assets in the instrumentation reporting unit of $2.5 million. The impairment was primarily from lower margins on the forecasted projections due to product mix. The impairment test for the remaining reporting units resulted in the fair value exceeding the carrying value, passing the quantitative impairment test.

Restructuring and Related Activities [Abstract]
Restructuring Costs	Restructuring Costs Restructuring costs reflect the cost reduction programs implemented by the Company. Restructuring costs are expensed during the period in which the Company determines it will incur those costs and all requirements for accrual are met. Because these costs are recorded based upon estimates, actual expenditures for the restructuring activities may differ from the initially recorded costs. If the initial estimates are too low or too high, the Company could be required to either record additional expense in future periods or to reverse part of the previously recorded charges. The Company recorded restructuring costs of $0.9 million, $2.3 million, and $0.3 million during the years ended December 31, 2020, 2019, and 2018, respectively. In 2020 and 2018, restructuring costs were comprised primarily of employee termination costs, including severance and statutory retirement allowances, and were incurred in connection with various cost reduction programs. In 2019, restructuring costs included $1.2 million of employee termination costs, including severance and statutory retirement allowances incurred in connection with various cost reduction programs, and $1.1 million of other exit costs, including asset write downs and an impairment of a right of use asset associated with the closure and downsizing of facilities as part of the manufacturing transitions of the Company's force sensors products to facilities in India and China. The following table summarizes the activity to date related to these programs in the accrued restructuring liability, which is comprised of the activity associated primarily with the employee termination costs. The accrued restructuring liability balance as of December 31, 2020 and 2019, respectively, is included in other accrued expenses in the accompanying consolidated balance sheets (in thousands) : December 31, 2020 2019 Balance at beginning of year $ 604 $ 159 Restructuring charges 918 1,559 Adjustment for adoption of ASU 2016-02 — (69) Cash payments (1,458) (1,064) Foreign currency translation (1) 19 Balance at end of year $ 63 604

On December 22, 2017, the SEC staff issued SAB 118 which provides for a measurement period of one year from the enactment date to finalize the accounting for effects of the 2017 Tax Act. Consistent with that guidance, the Company had provisionally determined the tax cost of the one-time transition tax under the 2017 Tax Act to be approximately $2.2 million. In accordance with SAB 118, the financial reporting impact of the 2017 Tax Act was completed in the fourth quarter of 2018 resulting in a net $0.8 million increase in tax expense caused by a decrease in the transition tax and an increase in the valuation allowance. The 2017 Tax Act subjects a U.S. shareholder to tax on global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in the future years or provide for tax expense related to GILTI in the year the tax is incurred. The Company has elected to recognize tax expense related to GILTI in the year the tax is incurred. The Company recognized approximately $14.3 million and $12.9 million of GILTI income for the years ended December 31, 2020 and 2019, respectively. The U.S. tax on the GILTI income was fully offset by foreign tax credits associated with GILTI and U.S. operating losses exclusive of GILTI. Any excess foreign tax credits associated with GILTI are lost and cannot be carried forward to future years. The Company would have generated a net operating loss for U.S. federal income tax purposes but for the effects of the GILTI provision. Deferred income taxes represent the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows (in thousands) : December 31, 2020 2019 Deferred tax assets: Pension and other postretirement costs $ 4,296 $ 3,770 Inventories 2,327 2,095 Net operating/capital loss and interest carryforwards 13,082 11,895 Tax credit carryforwards 1,994 1,431 Deferred compensation 2,930 2,865 Other accruals and reserves 3,420 3,362 Book over tax depreciation 93 — Total gross deferred tax assets 28,142 25,418 Less: valuation allowance (16,946) (14,867) 11,196 10,551 Deferred tax liabilities: Tax over book depreciation — (290) Investment in subsidiary (1,927) (1,845) Intangible assets, including tax deductible goodwill (5,657) (5,745) Total gross deferred tax liabilities (7,584) (7,880) Net deferred tax assets $ 3,612 $ 2,671 In 2015, the Company established a valuation allowance with respect to substantially all of its U.S. deferred tax assets due to uncertainty regarding the realization of these assets. Throughout 2019 and 2020, the Company reassessed its ability to realize its U.S. and other deferred tax assets by considering both positive and negative evidence regarding realization. The most significant negative evidence is continuing cumulative operating losses in the U.S. The impact of the acquisitions of Stress-Tek, Pacific Instruments and DSI was also considered in determining the realization of the U.S. deferred tax assets. Other aspects, such as operating results, additional interest expense and additional tax deductions related to the Stress-Tek acquisition, were also considered. The Company also considered positive evidence such as tax planning strategies and the projected benefits of our restructuring efforts. However, there was insufficient positive evidence to overcome the negative evidence. In November 2019, the Company acquired Dynamic Systems, Inc. ("DSI"), a U.S. company. DSI's opening balance sheet included $17 million of gross deferred tax liabilities, including $4.1 million of indefinite-lived liabilities. The acquisition contributed to a $2.5 million net reduction in valuation allowance and current tax benefit for the Company in 2019. In the fourth quarter of 2020, the Company completed the purchase accounting for the acquisition of DSI, which resulted in the recognition of additional deferred tax assets of $1.7 million and a corresponding increase in valuation allowance. Overall, the cumulative losses and the acquisition impacts still indicate that realization of our U.S. deferred tax assets remains uncertain such that the Company cannot conclude that it is "more likely than not" that the deferred tax assets will be recoverable. We will continue to monitor the realization of U.S. deferred tax assets and reduce the valuation allowance if, and when, sufficient positive evidence of realization exists. At December 31, 2020 and 2019, the valuation allowance on U.S. deferred tax assets was approximately $14.9 million and $11.8 million, respectively. The net change in valuation allowance was approximately $3.2 million. The valuation allowance related to state taxes was $0.7 million and $0.8 million expense for the years ended December 31, 2020 and 2019, respectively. The Company also has valuation allowances of $2.0 million and $3.1 million at December 31, 2020 and 2019, respectively, with respect to certain foreign net operating loss and capital loss carryforwards. Significant valuation allowances are as follows (in thousands) : December 31, Jurisdiction 2020 2019 U.S. federal $ 5,816 $ 3,395 U.S. state (net of U.S. federal tax benefit) 9,090 8,411 Israel - capital losses 1,390 2,457 The following table summarizes significant net operating losses and credit carryforwards as of December 31, 2020 (in thousands): December 31, Jurisdiction 2020 Expiring U.S. federal net operating losses $ 5,548 No expiration U.S. federal net operating loss 315 2036 U.S. federal interest expense carryover 5,191 No expiration U.S. foreign tax credit 1,734 2026 - 2040 U.S. state net operating losses 102,090 2024 - 2040 Israel capital losses 6,042 No expiration The U.S. federal net operating losses shown above are pre-acquisition losses of DSI. The utilization of these losses is limited to $765 thousand per year pursuant to Internal Revenue Code ("IRC") Section 382. In addition, utilization of U.S. federal net operating losses is taken into account before the GILTI deduction allowable by IRC Section 250. Undistributed earnings of the Company’s foreign subsidiaries amounted to approximately $178.2 million at December 31, 2020 compared to $159.0 million at December 31, 2019. As a result of the 2017 Tax Act, in 2017 the Company had provided for a deferred tax liability of approximately $1.8 million of withholding tax associated with a planned cash distribution of approximately $25.5 million. As of December 31, 2020, other than the planned cash distribution of $14.1 million, substantially all of the remaining undistributed earnings are considered to be indefinitely reinvested and accordingly no provision has been made with respect to these earnings for incremental foreign income taxes, state income taxes or foreign withholding taxes. If those earnings were distributed to the U.S., the Company could be subject to incremental foreign income taxes, state income taxes, and withholding taxes. Determination of the amount of unrecognized deferred tax liability is not practicable because of the uncertainty regarding the timing of any such distribution and the impact on existing valuation allowances. In addition to the $1.5 million, additional withholding taxes of approximately $18.0 million are estimated to be payable upon remittance of the remaining previously unremitted earnings as of December 31, 2020. Net income taxes paid were $4.3 million, $11.1 million, and $7.3 million for the years ended December 31, 2020, 2019, and 2018, respectively. The Company and its subsidiaries are subject to income taxes imposed by the U.S., various states, and the foreign jurisdictions in which we operate. Each jurisdiction establishes rules that set forth the years which are subject to examination by its tax authorities. While the Company believes the tax positions taken on its tax returns for each jurisdiction are supportable, they may still be challenged by the jurisdiction's tax authorities. In anticipation of such challenges, the Company has established reserves for tax-related uncertainties. These liabilities are based on the Company’s best estimate of the potential tax exposures in each respective jurisdiction. It may take a number of years for a final tax liability in a jurisdiction to be determined, particularly in the event of an audit. If an uncertain matter is determined favorably, there could be a reduction in the Company’s tax expense. An unfavorable determination could increase tax expense and could require a cash payment, including interest and penalties. The following table summarizes changes in the Company's gross liabilities, excluding interest and penalties, associated with unrecognized tax benefits (in thousands) : December 31, 2020 2019 2018 Balance at beginning of year $ 1,355 $ 912 $ 823 Addition based on tax positions related to current year 51 144 189 Addition based on tax positions related to prior years — 668 182 Reduction based on tax positions related to prior years (57) (32) (98) Currency translation adjustments 92 3 (28) Reduction for settled tax examinations (73) — — Reduction for payments made (22) (134) — Reduction for lapses of statute of limitations (102) (206) (156) Balance at end of year $ 1,244 $ 1,355 $ 912 The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. Related to the unrecognized tax benefits noted above, for the years ended December 31, 2020, December 31, 2019 and December 31, 2018, the Company accrued total penalties and interest of $0.0 million, $0.0 million and $0.1 million, respectively. As of December 31, 2020, December 31, 2019 and December 31, 2018, accrued penalties and interest were $0.1 million, $0.1 million and $0.1 million, respectively. Included in the balance of unrecognized tax benefits as of December 31, 2020, 2019, and 2018 is $1.2 million, $1.4 million, and $0.9 million, respectively, of tax benefits that, if recognized, would impact the effective tax rate. The Company believes that it is reasonably possible that an increase in unrecognized tax benefits related to foreign exposures of between $0.1 million and $0.2 million may be necessary in 2020. As of December 31, 2020, the Company anticipates that it is reasonably possible that it will reverse less than $0.1 million of its current unrecognized tax benefits within the next calendar year due to the expiration of the statute of limitations in certain jurisdictions. None of the unrecognized tax benefits the Company expects to reverse in 2021 due to statute lapses are covered by the Tax Matters Agreement. The Company and its subsidiaries file U.S. federal income tax returns, as well as income tax returns in various state, local, and foreign jurisdictions. The Company files federal, state, and local income tax returns on a combined, unitary, or stand-alone basis. The statute of limitations in those jurisdictions generally ranges from 3 to 4 years. Additionally, the Company's foreign subsidiaries file income tax returns in the countries in which they have operations and the statutes of limitations in those jurisdictions generally range from 3 to 10 years. During the fourth quarter of 2020, the Company concluded a tax examination in Israel for one of its subsidiaries covering 2015. The conclusion of the audit resulted in no significant change in tax and a release of $0.1 million of reserves for uncertain tax positions for that year, including accrued interest. During the second and third quarters of 2019, the Company concluded tax examinations in Taiwan and Belgium, respectively, for two of its subsidiaries, covering the years 2016 and 2017. The conclusion of the tax examinations resulted in no significant change in tax. During the fourth quarter of 2018, the Company concluded a tax examination in Germany for one of its subsidiaries, covering the years 2015 and 2016. The conclusion of the tax examination resulted in no significant change in tax. The Company is subject to ongoing income tax audits, administrative appeals and judicial proceedings in India spanning a number of years.

The proceeds of the 2020 Revolving Facility may be used for working capital and general corporate purposes, and a portion of such proceeds was used to refinance the Company’s existing revolving credit facility in the amount of $34.0 million and the Company’s existing term loans as follows: (1) the “2015 U.S. Closing Date Term Facility” in an aggregate principal amount of $2.0 million; and (2) the "2015 U.S. Delayed Draw Term Facility" in an aggregate principal amount of $5.0 million. The aggregate principal amount of the 2020 Revolving Facility may be increased by a maximum of $25.0 million upon the request of the Company, subject to the terms of the 2020 Credit Agreement. The 2020 Credit Agreement terminates on March 20, 2025. The 2020 Credit Agreement replaced the 2015 Credit Agreement. Interest payable on amounts borrowed under the 2020 Revolving Facility is based upon, at the Company’s option, (1) the greatest of: the Agent’s prime rate, the Federal Funds rate, or a LIBOR floor (the “Base Rate”), or (2) LIBOR or CDOR plus a specified margin. An interest margin of 0.25% is added to Base Rate loans. Depending upon the Company’s leverage ratio, an interest rate margin ranging from 1.50% to 2.75% per annum is added to the applicable LIBOR or CDOR rate to determine the interest payable on the LIBOR or CDOR loans. The Company is required to pay a quarterly fee of 0.25% per annum to 0.40% per annum on the unused portion of the 2020 Revolving Facility, which is determined based on the Company’s leverage ratio each quarter. Additional customary fees apply with respect to letters of credit. The obligations of the Company under the 2020 Credit Agreement are secured by pledges of stock in certain domestic and foreign subsidiaries, as well as guarantees by substantially all of the Company’s domestic subsidiaries. The obligations of the Company and the guarantors under the 2020 Credit Agreement are secured by substantially all the assets (excluding real estate) of the Company and such guarantors. The 2020 Credit Agreement restricts the Company from paying cash dividends and requires the Company to comply with other customary covenants, representations, and warranties, including the maintenance of specific financial ratios. The financial maintenance covenants include an interest coverage ratio and a leverage ratio. The Company was in compliance with its financial maintenance covenants at December 31, 2020. If the Company is not in compliance with any of these covenant restrictions, the credit facility could be terminated by the lenders, and all amounts outstanding pursuant to the credit facility could become immediately payable.

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits	Pensions and Other Postretirement Benefits Defined Benefit Plans Employees of the Company participate in various defined benefit pension and other postretirement benefit plans. U.S. Pension Plan The Vishay Precision Group Non-Qualified Retirement Plan, like all nonqualified plans, is considered to be unfunded. The Company maintains a nonqualified trust, referred to as a “rabbi” trust, to fund benefits under this plan. Rabbi trust assets are subject to creditor claims under certain conditions and are not the property of employees. Therefore, they are accounted for as other noncurrent assets within the consolidated balance sheets. The assets held in the rabbi trust are invested in money market funds and company-owned life insurance policies. The consolidated balance sheets include assets held in trust related to the nonqualified pension plan of $1.9 million at December 31, 2020 and $1.7 million at December 31, 2019, and the related liabilities of $2.7 million and $2.4 million at December 31, 2020 and 2019, respectively. The Vishay Precision Group Non-Qualified Retirement Plan is frozen. Accordingly, no new employees may participate in the plan, no further participant contributions are permitted, and no further benefits accrue. Benefits accumulated prior to the freezing of the U.S. pension plan will be paid to employees upon retirement, and the Company will likely need to make additional cash contributions to the rabbi trust to fund this accumulated benefit obligation. Non-U.S. Pension Plans The Company provides pension and similar benefits to employees of certain non-U.S. subsidiaries consistent with local practices. Pension benefits earned are generally based on years of service and compensation during active employment. In 2018, the Company undertook several measures to de-risk the UK pension plan. The first measure was to freeze the plan, with no new participants permitted and no further benefits accrue. The second measure was to execute an enhanced transfer value exercise to transfer pension benefits outside of the plan. As a result, the Company incurred $0.7 million of expense related to these de-risking measures. The following table sets forth a reconciliation of the benefit obligation, plan assets, and funded status related to pension plans (in thousands) : December 31, 2020 December 31, 2019 U.S. Non-U.S. U.S. Non-U.S. Change in benefit obligation: Benefit obligation at beginning of year $ 2,414 $ 24,857 $ 2,160 $ 21,762 Service cost (adjusted for actual employee contributions) — 402 — 336 Interest cost 70 442 85 535 Actuarial (gains) losses 338 1,863 248 1,922 Benefits paid (75) (659) (79) (777) Curtailments and settlements — (95) — (25) Plan amendments and other — — — 573 Currency translation — 1,278 — 531 Benefit obligation at end of year $ 2,747 $ 28,088 $ 2,414 $ 24,857 Change in plan assets: Fair value of plan assets at beginning of year $ — $ 16,420 $ — $ 14,501 Actual return on plan assets — 734 — 1,338 Company contributions 75 919 79 953 Benefits paid (75) (659) (79) (777) Curtailments and settlements — — — (25) Currency translation — 743 — 430 Fair value of plan assets at end of year $ — $ 18,157 $ — $ 16,420 Funded status at end of year $ (2,747) $ (9,931) $ (2,414) $ (8,437) Actuarial losses incurred in 2020 related to our U.S. and non-U.S. plans are primarily the result of a decrease in the discount rate assumptions used to estimate the benefit obligations as of December 31, 2020 compared to December 31, 2019. Actuarial losses incurred in 2019 related to our U.S. and non-U.S. plans are primarily the result of a decrease in the discount rate assumptions used to estimate the benefit obligations as of December 31, 2019 compared to December 31, 2018. Amounts recognized in the consolidated balance sheets consist of the following pre-tax amounts (in thousands) : December 31, 2020 December 31, 2019 U.S. Non-U.S. U.S. Non-U.S. Other accrued expenses $ (105) $ (240) $ (98) $ (325) Accrued pension and other postretirement costs $ (2,642) $ (9,691) $ (2,316) $ (8,112) Accumulated other comprehensive loss $ 823 $ 9,068 $ 594 $ 5,969 $ (1,924) $ (863) $ (1,820) $ (2,468) Unrecognized actuarial gains and losses arise from several factors, including experience and assumption changes with respect to the obligations and from the difference between expected returns and actual returns on plan assets. Actuarial items consist of the following (in thousands) : December 31, 2020 December 31, 2019 U.S. Non-U.S. U.S. Non-U.S. Unrecognized net actuarial loss $ 823 $ 9,008 $ 594 $ 5,906 Unrecognized prior service cost — 60 — 62 Unamortized transition obligation — — — 1 $ 823 $ 9,068 $ 594 $ 5,969 The following table sets forth additional information regarding the projected and accumulated benefit obligations for the pension plans (in thousands) : December 31, 2020 U.S. Non-U.S. Accumulated benefit obligation, all plans $ 2,747 $ 25,148 Plans for which the accumulated benefit obligation exceeds plan assets: Projected benefit obligation $ 2,747 $ 25,107 Accumulated benefit obligation $ 2,747 $ 24,099 Fair value of plan assets — $ 16,259 December 31, 2019 U.S. Non-U.S. Accumulated benefit obligation, all plans $ 2,414 $ 23,686 Plans for which the accumulated benefit obligation exceeds plan assets: Projected benefit obligation $ 2,414 $ 23,386 Accumulated benefit obligation $ 2,414 $ 22,743 Fair value of plan assets — $ 14,983 Unrecognized gains and losses are amortized into future net periodic pension cost using the 10% corridor method over the expected remaining service life of the employee group.

The following weighted-average assumptions were used to determine benefit obligations at December 31 of the respective years: 2020 2019 U.S. Non-U.S. U.S. Non-U.S. Discount rate 2.11 % 1.29 % 2.97 % 1.86 % Rate of compensation increase N/A 2.77% N/A 1.20% Expected return on plan assets N/A 2.66 % N/A 3.56 % The following weighted-average assumptions were used to determine the net periodic pension costs for the years ended December 31, 2020 and 2019: 2020 2019 U.S. Non-U.S. U.S. Non-U.S. Discount rate 2.97 % 1.86 % 3.99 % 2.47 % Rate of compensation increase N/A 1.20% N/A 3.08 % Expected return on plan assets N/A 3.56 % N/A 2.70 % The plans’ expected return on assets is based on management’s expectation of long-term average rates of return to be achieved by the underlying investment portfolios. In establishing this assumption, management considers historical and expected returns for the asset classes in which the plans are invested, advice from pension consultants and investment advisors, and current economic and capital market conditions. The investment mix between equity securities and fixed income securities is based upon achieving a desired return, balancing higher return, more volatile equity securities, and lower return, less volatile fixed income securities. The target allocation of plan assets approximates the actual allocation of plan assets at December 31, 2020 and 2019. Plan assets are comprised of: December 31, 2020 December 31, 2019 U.S. Non-U.S. U.S. Non-U.S. Equity securities — 48 % — 48 % Fixed income securities — 39 % — 42 % Cash and cash equivalents — 13 % — 10 % Total — 100 % — 100 % The Company maintains defined benefit retirement plans in certain of its subsidiaries. The assets of the plans are measured at fair value. Equity securities held by the defined benefit retirement plans consist of equity securities that are valued based on quoted market prices on the last business day of the year. The fair value measurement of the equity securities is considered a Level 2 measurement within the fair value hierarchy. Fixed income securities held by the defined benefit retirement plans consist of government bonds and corporate notes that are valued based on quoted market prices on the last business day of the year. The fair value measurement of the fixed income securities is considered a Level 2 measurement within the fair value hierarchy. Cash held by the defined benefit retirement plans consists of deposits on account in various financial institutions. The carrying amount of the cash approximates its fair value. A summary of the Company’s pension plan assets for each fair value hierarchy level are as follows for the periods presented (see Note 16 for further description of the levels within the fair value hierarchy (in thousands)) : As of December 31, 2020 Fair value measurements at reporting date using: Total Fair Value Level 1 Inputs Level 2 Inputs Level 3 Inputs Defined benefit pension plan assets Equity securities $ 8,779 $ — $ 8,779 $ — Fixed income securities 7,700 — 7,700 — Cash and cash equivalents 1,678 1,678 — — $ 18,157 $ 1,678 $ 16,479 $ — As of December 31, 2019 Fair value measurements at reporting date using: Total Fair Value Level 1 Inputs Level 2 Inputs Level 3 Inputs Defined benefit pension plan assets Equity securities $ 7,796 $ — $ 7,796 $ — Fixed income securities 7,703 — 7,703 — Cash and cash equivalents 921 921 — — $ 16,420 $ 921 $ 15,499 $ — Estimated future benefit payments are as follows (in thousands) : US Pension Non-US 2021 $ 105 $ 1,068 2022 106 784 2023 135 1,334 2024 134 853 2025 135 1,358 2025 - 2028 757 4,993 The Company anticipates making contributions to its funded and unfunded pension of approximately $1.4 million during 2021. Other Postretirement Benefit Plans In the U.S., the Company maintains two unfunded non-pension other postretirement benefit plans (“OPEB”) which are funded as costs are incurred. These plans provide medical and death benefits to retirees. The following table sets forth a reconciliation of the benefit obligation, plan assets, and funded status related to other postretirement benefit plans (in thousands) : OPEB Plans December 31, 2020 2019 Change in benefit obligation: Benefit obligation at beginning of year $ 4,633 $ 4,645 Service cost (adjusted for actual employee contributions) 123 126 Interest cost 133 180 Contributions by participants 25 — Actuarial gains (1,498) (131) Benefits paid (249) (187) Plan amendments and other 410 — Benefit obligation at end of year $ 3,577 $ 4,633 Change in plan assets: Fair value of plan assets at beginning of year $ — $ — Company contributions 224 187 Contributions by participants 25 — Benefits paid (249) (187) Fair value of plan assets at end of year $ — $ — Funded status at end of year $ (3,577) $ (4,633) Actuarial gains incurred in 2020 related to our post-retirement plans are primarily the result of a prior year adjustment of $763, changes in medical claims and age variance assumptions, net of a decrease in the discount rate assumptions used to estimate the benefit obligations as of December 31, 2020 compared to December 31, 2019. Actuarial gains incurred in 2019 related to our post-retirement plans are primarily the result of a decrease in the discount rate assumptions used to estimate the benefit obligations as of December 31, 2019 compared to December 31, 2018.

The impact of a one-percentage-point change in assumed health care cost trend rates on the net periodic benefit cost and postretirement benefit obligation is not material. Estimated future benefit payments are as follows (in thousands) : OPEB 2021 $ 266 2022 $ 240 2023 $ 197 2024 $ 221 2025 $ 210 2025 - 2028 $ 1,044 As the plans are unfunded, the Company's anticipated contributions for 2021 are equal to the estimated benefit payment. Other Retirement Obligations The Company participates in various other defined contribution plans based on local law or custom. The Company periodically makes contributions to these plans. At December 31, 2020 and 2019, the consolidated balance sheets include $1.0 million and $0.9 million, respectively, within accrued pension and other postretirement costs related to these plans. Most of the Company’s U.S. employees are eligible to participate in 401(k) savings plans which provide company matching under various formulas. The Company’s matching expense for the plans was $0.8 million, $0.7 million, and $0.7 million for the years ended December 31, 2020, 2019, and 2018, respectively. No material amounts are included in the consolidated balance sheets related to unfunded 401(k) contributions. Certain key employees participate in a nonqualified deferred compensation plan, which allows these employees to defer a portion of their compensation until retirement, or elect shorter deferral periods. The accompanying consolidated balance sheets include a liability within other noncurrent liabilities related to these deferrals. The Company maintains a nonqualified trust, referred to as a “rabbi” trust, to fund payments under this plan. Rabbi trust assets are subject to creditor claims under certain conditions and are not the property of employees. Therefore, they are accounted for as other noncurrent assets within the consolidated balance sheets. The assets held in the rabbi trust are invested in money market funds and company-owned life insurance policies. The consolidated balance sheets include assets held in trust related to the nonqualified deferred compensation plan of $3.7 million at December 31, 2020 and $3.5 million at December 31, 2019, and the related liabilities of $5.4 million and $4.9 million at December 31, 2020 and 2019, respectively.

Share-Based Compensation

Share-Based Compensation	12 Months Ended
	Dec. 31, 2020
Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation The Amended and Restated Vishay Precision Group, Inc. Stock Incentive Plan (as amended and restated, the “Plan”) permits the issuance of up to 1,000,000 shares of common stock. At December 31, 2020, the Company had reserved 371,637 shares of common stock for future grant of equity awards (restricted stock, unrestricted stock, restricted stock units (“RSUs”), or stock options). If any outstanding awards are forfeited by the holder, the underlying shares would be available for future grants under the Plan. Restricted Stock Units Pursuant to the Plan, the Company issued RSUs to board members, executive officers, and certain employees of the Company during 2020. The amount of compensation cost related to share-based payment transactions is measured based on the grant-date fair value of the equity instruments issued. VPG determines compensation cost for RSUs based on the grant-date fair value of the underlying common stock. Compensation cost is recognized over the period that the participant provides service in exchange for the award. The Company recognizes compensation cost for RSUs that are expected to vest and for which performance criteria are expected to be met. On March 5, 2020, VPG’s three current executive officers were granted annual equity awards in the form of RSUs, of which 75% are performance-based. The awards have an aggregate target grant-date fair value of $1.2 million were comprised of 44,269 RSUs. Twenty-five percent of these awards will vest on January 1, 2023, subject to the executives' continued employment. The performance-based portion of the RSUs will also vest on January 1, 2023, subject to the executives' continued employment and the satisfaction of certain performance objectives relating to three-year cumulative “adjusted free cash flow” and net earnings goals, each weighted equally. The awards issued in 2019 and 2018 have similar allocations and vesting criteria. On March 16, 2020, certain VPG employees were granted annual equity awards in the form of RSUs, of which 75% are performance-based. The awards have an aggregate target grant-date fair value of $0.4 million and were comprised of 18,940 RSUs. Twenty-five percent of these awards will vest on January 1, 2023 subject to the employees' continued employment. The performance-based portion of the RSUs will also vest on January 1, 2023, subject to the employee's continued employment and the satisfaction of certain performance objectives relating to three-year cumulative earnings goals and cash flow goals. On May 21, 2020, the Board of Directors approved the issuance of an aggregate of 15,564 RSUs to the independent board members of the Board of Directors and to the non-executive Chairman of the Board of Directors. The awards have an aggregate grant-date fair value of $0.3 million and will vest on the earlier of the 2021 Annual Stockholders meeting or May 21, 2021, subject to the directors' continued service on the Board of Directors. Vesting of equity awards may be subject to acceleration under certain circumstances. RSU activity is presented below (number of RSUs in thousands) : Years ended December 31, 2020 2019 2018 Number Weighted Number Weighted Number Weighted Outstanding: Beginning of year 212 $ 25.97 265 $ 17.64 417 $ 14.57 Granted 79 24.16 73 35.27 74 28.20 Vested (81) 19.02 (75) 15.27 (86) 16.75 Forfeited (5) 15.75 (51) 11.49 (140) 14.70 End of year 205 $ 28.23 212 $ 25.97 265 $ 17.64 The fair value of the RSUs vested during 2020 is $2.3 million. Included in the 2020, 2019 and 2018 activity are RSU's forfeited as a result of performance objectives not being met. These awards are therefore available for future grants under the Plan.

During the fourth quarter of 2020, a net adjustment reducing share-based compensation expense by $0.1 million was recorded, based on the evaluation of performance objectives associated with awards granted in 2018, 2019 and 2020. It was determined that certain objectives were not likely to be fully met, necessitating a reversal of certain compensation expense associated with those awards. This was partially offset by additional share based compensation expense being recorded for certain objectives being fully met, which had been reversed in the prior year. During 2019, it was determined that certain performance objectives associated with awards granted in 2017, 2018 and 2019 were not likely to be fully met, necessitating a reversal of certain compensation expense associated with those awards. As a net result, adjustments decreasing share based compensation expense totaling $0.8 million were recorded during the year based on anticipated performance levels. The deferred tax benefit on share-based compensation expense was $0.0 million , $0.1 million, and $0.0 million for the years ended December 31, 2020, 2019, and 2018, respectively. As of December 31, 2020, the Company had $0.8 million of unrecognized share-based compensation expense related to share-based awards that will be recognized over a weighted-average period of approximately 1.3 years.

Commitments and Contingencies Disclosure [Abstract]
Commitments Contingencies and Concentrations	Commitments, Contingencies, and Concentrations Litigation The Company is subject to various legal proceedings that constitute ordinary, routine litigation incidental to its business. The Company is of the opinion that the disposition of these proceedings will not have a material adverse effect on its business or its financial condition, results of operations, and cash flows. Executive Employment Agreements The Company has employment agreements with its executive officers which outline base salary, incentive compensation, and equity-based compensation. The employment agreements with the Company's executive officers also provide for incremental compensation in the event of termination without cause or resignation for good reason. Sources of Supplies Although most materials incorporated in the Company’s products are available from a number of sources, certain materials are available only from a relatively limited number of suppliers. Some of the most highly specialized materials for the Company’s sensors are sourced from a single vendor. The Company maintains a safety stock inventory of certain critical materials at its facilities. Certain metals used in the manufacture of the Company’s products are traded on active markets, and can be subject to significant price volatility. Market Concentrations No single customer comprises greater than 10% of net revenues. The vast majority of the Company’s products are used in the broad industrial market, with selected uses in military and aerospace, medical, agriculture, and construction. Within the broad industrial segment, the Company’s products serve wide applications in the waste management, bulk hauling, logging, scale manufacturing, engineering systems, pharmaceutical, oil, chemical, steel, paper, and food industries. Credit Risk Concentrations Financial instruments with potential credit risk consist principally of cash and cash equivalents, accounts receivable, and notes receivable. The Company maintains cash and cash equivalents with various major financial institutions. Concentrations of credit risk with respect to receivables are generally limited due to the Company’s large number of customers and their dispersion across many countries and industries. At December 31, 2020 and 2019, the Company had no significant concentrations of credit risk. Geographic Concentrations At December 31, 2020 and 2019, a significant percentage of the Company’s cash and cash equivalents are held outside the United States. See the following table for the percentage of cash and cash equivalents by region at December 31, 2020 and December 31, 2019: December 31, 2020 2019 Asia 18 % 23 % United States 10 % 7 % Israel 26 % 28 % Europe 16 % 14 % United Kingdom 18 % 17 % Canada 12 % 11 % Total 100 % 100 %

Segment Reporting [Abstract]
Segment and Geographic Data	Segment and Geographic Data VPG reports in three product segments: the Foil Technology Products segment, the Force Sensors segment, and the Weighing and Control Systems segment. The Foil Technology Products reporting segment is comprised of the foil resistor and strain gage operating segments. The Force Sensors reporting segment is comprised of transducers, load cells, and modules. The Weighing and Control Systems reporting segment is comprised of complete systems which include load cells and instrumentation for weighing, force control and force measurement for a variety of uses such as process control and on-board weighing applications. VPG evaluates reporting segment performance based on multiple performance measures including gross profits, revenues, and operating income, exclusive of certain items. Management believes that evaluating segment performance, excluding items such as restructuring and severance costs, and other items is meaningful because it provides insight with respect to the intrinsic operating results of VPG. The accounting policies of the segments are the same as those described in the summary of significant accounting policies (see Note 1). Reporting segment assets are the owned or allocated assets used by each segment. Products are transferred between segments on a basis intended to reflect, as nearly as practicable, the market value of the products.

The change in foreign exchange gains / (losses) during the period, as compared to the prior year period, is primarily due to fluctuations in the Israeli shekel. The change in the dollar-shekel exchange rate, particularly in the fourth quarter of 2020, resulted in an unfavorable foreign exchange impact primarily related to the shekel-denominated lease liability for a new Foil Technology Products facility in Israel . Pension expense represents the net periodic benefit cost excluding the service cost. In 2018, the Company recognized a settlement loss of $0.7 million related to measures taken to de-risk the UK pension schemes as discussed in Note 9 to the consolidated financial statements. Included in Other for the year ended December 31, 2019, is a one-time $0.8 million gain on liquidation of one of the Company's subsidiaries.

Under the Severance Pay Law, the severance payment is calculated as one month salary for each year of employment, or a portion thereof. Part of the subsidiary's liability for severance pay is covered by the provisions of Section 14 of the Severance Pay Law ("Section 14"). Under Section 14, employees are entitled to monthly deposits, at a rate of 8.33% of their monthly salary, contributed on their behalf to their insurance funds. Payments in accordance with Section 14 release the subsidiary from any future severance payments in respect of those employees. As a result, the Company does not recognize any liability for severance pay due to these employees and the deposits under Section 14 are not recorded as an asset in the Company's balance sheet. For the subsidiary's employees in Israel who are not subject to Section 14, the Company calculated the liability for severance pay pursuant to the Severance Pay Law based on the most recent salary of these employees multiplied by the number of years of employment as of the balance sheet date. The Company recorded as expenses the increase in the severance liability, net of earnings (losses) from the related investment fund. The subsidiary's liability was partially funded by monthly payments deposited with insurers and the value of these deposits is recorded as an asset on the Company's balance sheet. Any unfunded amounts would be paid from operating funds and are covered by a provision established by the subsidiary. The accompanying consolidated balance sheets at December 31, 2020 and December 31, 2019 include a $8.3 million and $8.0 million liability, respectively, associated with Israeli severance requirements in other liabilities. Executive Severance During the second fiscal quarter of 2019, the Company recorded $0.6 million of severance costs associated with the resignation of an executive officer of the Company. The severance costs consisted of payments and other benefits as specified in the executive officer's separation agreement.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC Topic 820, Fair Value Measurements and Disclosures, establishes a valuation hierarchy of the inputs used to measure fair value. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the Company’s own assumptions. An asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following tables provide the financial assets and liabilities carried at fair value measured on a recurring basis (in thousands) : As of December 31, 2020 Fair value measurements at reporting date using: Total Fair Value Level 1 Inputs Level 2 Inputs Level 3 Inputs Assets: Assets held in rabbi trusts $ 5,601 $ 61 $ 5,540 $ — As of December 31, 2019 Fair value measurements at reporting date using: Total Fair Value Level 1 Inputs Level 2 Inputs Level 3 Inputs Assets: Assets held in rabbi trusts $ 5,169 $ 53 $ 5,116 $ — The Company maintains nonqualified trusts, referred to as “rabbi” trusts, to fund payments under deferred compensation and nonqualified pension plans. Rabbi trust assets consist primarily of marketable securities, classified as available-for-sale money market funds at December 31, 2020 and December 31, 2019, and company-owned life insurance assets. The marketable securities held in the rabbi trusts are valued using quoted market prices on the last business day of the year. The company-owned life insurance assets are valued in consultation with the Company’s insurance brokers using the value of underlying assets of the insurance contracts. The fair value measurement of the marketable securities held in the rabbi trust is considered a Level 1 measurement and the measurement of the company-owned life insurance assets is considered a Level 2 measurement within the fair value hierarchy. The fair value of the long-term debt, excluding capitalized deferred financing costs at December 31, 2020 and December 31, 2019 approximates its carrying value, as the revolving debt and term loans are reset monthly based on current market rates, plus a base rate as specified in the 2020 Credit Agreement. The fair value measurement of long-term debt is considered a Level 2 measurement. The Company’s financial instruments include cash and cash equivalents, accounts receivable, short-term notes payable, and accounts payable. The carrying amounts for these financial instruments reported in the consolidated balance sheets approximate their fair values.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Until July 6, 2010, VPG was part of Vishay Intertechnology, and the assets and liabilities consisted of those that Vishay Intertechnology attributed to its precision measurement and foil resistor businesses. Following the spin-off on July 6, 2010, VPG is an independent, publicly-traded company, and Vishay Intertechnology does not retain any ownership interest in VPG, although a common group of stockholders control a significant portion of the voting power of each company and the companies have three common board members. Subsequent to the spin-off, VPG and Vishay Intertechnology continue to share certain manufacturing locations. VPG owns one location in Japan at which it leases space to Vishay Intertechnology. Vishay Intertechnology owns one location in the United States, at which it leases space to VPG. Lease receipts and payments related to the shared facilities are immaterial.

Background and Summary of Sig_2

Background and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the individual entities in which the Company maintained a controlling financial interest. For those subsidiaries in which the Company’s ownership is less than 100 percent, the outside stockholders’ interests are shown as noncontrolling interests in the accompanying consolidated balance sheets. All transactions, accounts, and profits between individual members comprising the Company have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates.
Revenue Recognition	Revenue Recognition The Company derives substantially all of its revenue from product sales. The Company recognizes the vast majority of its sales at a point-in-time. It utilizes the core principle of recognizing revenue when the Company satisfies performance obligations as evidenced by the transfer of control of its products to the customer. Such revenues are derived from purchase orders and/or contracts with customers. Each contract has the promise to transfer the control of the products, each of which is individually distinct and is considered the identified performance obligation. As part of the decision to enter into each contract, the Company evaluates the customer’s credit risk, but its contracts do not have any significant financing components, as payment is generally due net 30 to 60 days after delivery. In accordance with contract terms, revenue from the Company’s product sales is recognized at the time of product shipment from its facilities or delivery to the customer location, as determined by the agreed upon shipping terms. Under the terms of some of its contracts, the Company may be required to perform certain installation services. These installation services are performed at the time of product delivery or at some point thereafter. The installation services do not significantly modify the product provided, and although the Company may be required contractually to provide these services, the installation services could be performed by a third party or the customer. Thus, these installation services are a distinct performance obligation. In most of the applicable contracts, this installation service element is immaterial in the context of the agreement. When the installation services are accounted for as a separate performance obligation, the Company allocates the transaction price to this element based on its relative standalone selling price. Given the specialized nature of the Company's products, the Company generally does not allow product returns. Shipping and handling costs are recorded to Costs of product sold when control of the product has transferred to the customer. The Company offers standard product warranties. Warranty related costs continue to be recognized as expense when the products are sold. Sales, value add and other taxes collected concurrent with revenue-producing activities are excluded from revenue. See Note 2 for further details on Revenues.
Research and Development Expense	Research and Development ExpensesResearch and development costs are expensed as incurred.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income tax expense in the period that includes the enactment date. The Company records net deferred tax assets to the extent it believes such assets will "more likely than not" be realized. In making this determination, the Company considers all positive and negative evidence, including historic earnings, projected future income, and cost-effective tax-planning strategies. When the Company determines that its ability to realize deferred tax assets is not "more likely than not", the Company adjusts its deferred tax asset valuation allowance, which increases income tax expense. The Company records uncertain tax positions on the basis of a two-step process in which the Company first determines whether it is "more likely than not" that the tax positions will be sustained based on the technical merits of the position and then measures those tax positions that meet the more-likely-than-not recognition threshold. The Company recognizes the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense in the accompanying consolidated statements of operations. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets. On December 22, 2017, the SEC staff issued SAB 118 to address the application of U.S. GAAP in situations when a registrant does not have all the necessary information available to prepare and analyze the accounting treatment for the proper recognition of the tax impact of the 2017 Tax Act. In accordance with SAB 118 guidance, the Company had recorded the provisional tax impacts related to the deemed distribution of foreign earnings and the expense for the revaluation of deferred tax assets and liabilities in its consolidated financial statements for the year ended December 31, 2017. In accordance with SAB 118, the financial reporting impact of the 2017 Tax Act was completed in the fourth quarter of 2018 resulting in a net increase in tax expense of $0.8 million.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include demand deposits and highly liquid investments with original maturities of three months or less when purchased. Highly liquid investments with maturities greater than three months are classified as short-term investments. There were no investments classified as short-term investments at December 31, 2020 or 2019.
Allowance For Credit Losses	Allowance for Credit LossesThe Company maintains an allowance for credit losses resulting from the inability of its customers to make required payments. In determining the amount of the allowance for credit losses, the Company considers historical loss data, customer specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data.
Inventories	Inventories Inventories are stated at the lower of cost, determined by the first-in, first-out method, or market based on net realizable value. Inventories are adjusted for estimated excess and obsolescence and written down to net realizable value based upon estimates of future demand, technology developments, and market conditions.
Property and Equipment	Property and EquipmentProperty and equipment is carried at cost and is depreciated principally by the straight-line method based upon the estimated useful lives of the assets. Machinery and equipment are being depreciated over useful lives of seven twenty three
Business Combinations	Business Combinations The Company allocates the purchase price of an acquired company, including when applicable, the fair value of contingent consideration between tangible and intangible assets acquired and liabilities assumed from the acquired businesses based on estimated fair values, with any residual of the purchase price recorded as goodwill. Third party appraisal firms and other consultants are engaged to assist management in determining the fair values of certain assets acquired and liabilities assumed. Estimating fair values requires significant judgments, estimates and assumptions, including but not limited to: discount rates, future cash flows and the economic lives of trade names, technology, customer relationships, property, plant and equipment, as well as income taxes. These estimates are based on historical experience and information obtained from the management of the acquired companies, and are inherently uncertain.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and indefinite-lived trademarks are tested for impairment at least annually, and whenever events or changes in circumstances occur indicating that it is "more likely than not" impairment may have been incurred. The Company has the option to first assess qualitative factors to determine whether it is "more likely than not" that the fair value of a reporting unit is less than its carrying amount as a basis for determining if it is necessary to perform the quantitative goodwill impairment test. However, if the Company concludes otherwise, then it is required to perform the quantitative impairment test by calculating the fair value of the reporting unit and comparing it against its carrying amount. If the fair value exceeds the carrying value, no further evaluation is required and no impairment loss is recognized. An impairment charge would be recognized to the extent the carrying amount of goodwill exceeds the reporting unit fair value. The indefinite-lived trade names are tested for impairment either by employing the qualitative approach outlined above, or by comparing the carrying value to the fair value based on current revenue projections of the related operations, under the relief from royalty method. Any excess carrying value over the applicable fair value is recognized as impairment. Any impairment would be recognized in the reporting period in which it has been identified. The Company's required goodwill and indefinite-lived asset annual impairment test is completed as of the first day of the fourth fiscal quarter each year. As more fully described in Note 4 to the consolidated financial statements, the 2020 annual impairment test resulted in an impairment charge in the fourth quarter of 2020. The 2019 annual impairment test resulted in no impairment. The 2018 annual impairment test resulted in an impairment charge in the fourth quarter of 2018. seven five seven five
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The carrying value of long-lived assets held-and-used, other than goodwill and indefinite-lived intangible assets, is evaluated when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from such asset group are separately identifiable and are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset group. Fair market value is determined primarily using present value techniques based on projected cash flows from the asset group. Losses on long-lived assets held-for-sale, other than goodwill and indefinite-lived intangible assets, are determined in a similar manner, except that fair market values are reduced for disposal costs.
Foreign Currency Translation	Foreign Currency Translation The Company has significant operations outside of the United States. The Company's operations in Europe, Canada, and certain locations in Asia primarily generate and expend cash in local currencies, and accordingly, these subsidiaries utilize the local currency as their functional currency. The Company’s operations in Israel and certain locations in Asia primarily generate cash in U.S. dollars, and accordingly, these subsidiaries utilize the U.S. dollar as their functional currency. For those subsidiaries where the local currency is the functional currency, assets and liabilities in the consolidated balance sheets have been translated at the rate of exchange as of the balance sheet date. Revenues and expenses are translated at the average exchange rate for the year. Translation adjustments do not impact the consolidated statements of operations and are reported as a separate component of accumulated other comprehensive loss within the statement of comprehensive income. Foreign currency transaction gains and losses are included in the results of operations. For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency financial statement amounts are remeasured into U.S. dollars. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in the consolidated statements of operations.
Share-Based Compensation	Share-Based Compensation Compensation costs related to share-based payments are recognized in the consolidated financial statements. The amount of compensation cost is measured based on the grant-date fair value of the equity instruments issued. For service-based awards, compensation cost is recognized over the period that an officer, employee, or non-employee director provides service in exchange for the award. The Company recognizes forfeitures as they occur. For performance based awards, the Company recognizes compensation cost for awards that are expected to vest based on whether performance criteria are expected to be met. For options and restricted stock units subject to graded vesting, the Company recognizes expense over the service period for each separately vesting portion of the award as if the award was comprised of multiple awards.
Leases	Leases The Company determines if an arrangement is or contains a lease at inception or modification of such agreement. The arrangement is or contains a lease if the contract conveys the right to control the use of the identified asset for a period in exchange for consideration. Lease right of use assets and liabilities are recognized based on the present value of future minimum lease payments over the expected term at commencement date. As the implicit rate is not determinable in most of the Company's leases, the Company's incremental borrowing rate is used as the basis to determine the present value of future lease payments. The expected lease terms include options to extend or terminate. The period which is subject to an option to extend the lease is included in the lease term if it is reasonably certain that the option will be exercised. Some of these leases contain variable payment provisions that depend on an index or rate, initially measured using the index or rate at the lease commencement date and are therefore not included in our future minimum lease payments. Variable payments are expensed in the periods incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. The Company uses the practical expedients to exclude from balance sheet reporting leases with initial terms of 12 months or less and to exclude non-lease components from lease right of use assets and corresponding liabilities.
Commitments and Contingencies	Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13, and subsequent related amendments to ASU 2016-13, replace the existing incurred loss impairment model with an expected loss model that requires the use of forward-looking information to calculate credit loss estimates. The Company adopted this ASU, effective January 1, 2020, using the modified retrospective approach, and the effect on the Company's consolidated condensed financial statements and related disclosures was not material. In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurements (Topic 820)." This ASU modifies the disclosures on fair value measurements by removing the requirements to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and the policy for timing of such transfers. The ASU expands the disclosure requirements for Level 3 fair value measurements, primarily focused on changes in unrealized gains and losses included in other comprehensive income. The Company adopted this ASU effective January 1, 2020, and the effect on the Company's disclosures in its consolidated financial statements was not material. In August 2018, the FASB issued ASU No. 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." This ASU amends Accounting Standards Codification ("ASC") 715 to add, remove and clarify disclosure requirements related to defined benefit and pension and other postretirement plans. The Company adopted this ASU effective January 1, 2020, and determined that the effect on the Company's disclosures in its consolidated financial statements was not material. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU No. ASU 2019-12, "Simplifying the Accounting for Income Taxes". This ASU amends Accounting Standards Codification ("ASC") 740 by removing certain exceptions to the general principles, clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020 and early adoption is permitted. The Company has not yet adopted this ASU.
